Embodiment 1
[0037] Embodiment 1: step 1): using methanol solution as a solvent to prepare a reference substance solution;
[0038] Step 2): Prepare the test solution after heating the content of Shenbei Guchang Capsules to reflux;
[0039] Step 3): Determination of the content of ginsenoside Re in the reference substance solution and the test sample solution by high performance liquid chromatography;
[0040] The chromatographic detection conditions are: using octadecylsilane bonded silica gel as filler; using acetonitrile as mobile phase A and water as mobile phase B for gradient elution; flow rate 1mL / min, detection wavelength 203nm; injection volume 20μl;
[0041] Further, the specific operation for preparing the reference substance solution in step 1) is: accurately weigh the ginsenoside Re reference substance, add methanol to dissolve, and obtain a reference substance solution with a concentration of 0.2 mg / mL;
[0042] Further, the specific operation of step 2):
[0043] Step 2) s...
